To all whom it may concern:

Be it known that I, HENRY G.Vo1o1rr, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to locks and latches.

The object of my invention is to produce a lock of the so-called unit type, that is, a lock in which'the several parts, including knobs, escutcheons, etc, may be assembled independently of the door to which the lock sucha lock I have devised improvements whereby the same may be very quickly applied to a door, the mortisestherein being formed with a single tool, such as a bit or auger.

Various other advantages and improvements will be apparent to a' mechanic skilled in this art by a reading of the following descriptionz v In the drawings, Figure 1 is a plan view, partly in section, of-my improved lock as it would appear in place on a door. Fig. 2 is a longitudinal section through substantially the center of the lock showing cera plane at 'a right angle to the plane of Fig. 1. Fig. 3 is a longitudinal section of a detail. Fig. 4 is a cross section on the plane of the line (v -m, Fig. 8. Figs. 5, 6, 7 and 8 each show two different views of different details.

1 represents the edge of a door, as shown. The mortise for the lock is formed by boring only two holes in the door stile. One

stile, the axis thereof being coincident with the axis of the knobs. The other hole is bored' into the edge of the door stile so as to intersect the middle of the transverse bore first referred to. V

2 represents a bolt, in this instance a spring latch bolt.

3 represents a face plate through which the bolt vQpasses. The face plate may be of any suitable design.

4 is a cylindrical guideand carrier for thebolt 2. The bolt21s arranged to reciprocate in the carrier 4.

5 is a spring within the carrier, and arranged to project the bolt 2.

6 is a block on the latch slide 6. The tail 7 is the tail of the bolt. The tail ofthe bolt is adjusted inconnection with the block 6 by being threaded therein.

8 is a lock nut.

The carrier 4 screws into the cylindrical main body or frame 9 and projects radially therefrom. The length of the carrier 4 and the adjustment of thclatch 2 determines the set back of the lock. The frame 9 is provided at one end with a side plate'lO.

11 is a rose or knob bearing adapted to the passage through the plate 10.

1.2 is a knob rotatably mounted in the rose 11.

13 is a frame in the form of a side plate which is arranged to s and on the opposite side ofthe door from the plate 10. This plate is adjustable to and fro relatively to plate 10 by screws which are merely shown in section at 1414, Fi 2.

15 15 is a knob which stands opposite the knob 12.

16 is a rose bearing for the knob 15, said bearing being mounted in the plate 13.

Any suitable adjustable connection may be provided between the knobs' 1215 whereby there will be no interference in the adjustment of the side plates 10--13 toward and from each other. As shown in the drawings, the knob 15 in this case represents the outside door knob and may be provided with the usual key controlled mechanism inclosed therein, thesame being indicated in dotted out-line. controlled locking mechanism is designed to control the operation of one roll back, in this instance indicated at 17. The knobs 19. 15 may control respectively the rollbacks 18-19. The roll-back 19 may have at one side thereof a notch or locking rccess 19 (see Fig. 8).

20 is a locking dog, the nose of which is adapted to be projected into the notch 19 whenever desired to prevent the turning of the outer knob 15. The dog. 20 may be mounted in any suitable way at the inner side of the lock where it is accessible from the inside of the door for manual manipulation. The particular method of mounting this dog is immaterial, although in this particular instance it is shown as mounted This key 1 to slide upon the inner surface of the inside side plate 10, the samebeing slotted at 10 to permit a projection from the slide 20 to pass through said slot so as to be provided with a suitable operating button to receive finger pressure, said operatingbutton be ing indicated in dotted lines at 21 is a spring pressed detent for the tionally holding the dog in either the in or the out position. i It will be observed that the guided is always held in definite position. relative to the knob 12 by reason of the fact that both the guide and the knob 12 are held in definite spaced relation by the main body or frame 9, -hence thelentire adjustment for.

- the purposesof associating thelock with doors of different thicknesses isaeifected through the shifting of the outer side plate and the outer knob and associated parts- The roll-backs 17, 18 and 19 are allarranged to operate independently, hence,

when the oiiter knob 15 is locked, the latch bolt 2 may'still be operated by the inner knob 12 or by the key back 17.

What I claim is: 7 v 1.
